I was running ZoneAlarm version 9, no problems. I got a popup asking me to install a new version. This wouldn't go away, so I eventually tried to install the new version, from the CNET websie. During this process, I was asked to permit deletion of the old version - I clicked on OK. About halfway through installing the new version, everything froze. The install window showed Not Responding, so I aborted the installation, and tried to download again.
However, I found that my internet connection had been disabled. After lengthy diagnostics, I find that my network adapters, both wireless and ethernet, have disappeared when I go to the cmd prompt and type in ipconfig/all .
How can I get my network adapters back? This only happened during the aborted ZoneAlarm install, so the problem must lie there.
